A method implemented in an audio system including a transducer having a magnetic element suitable for generating vibrations based on the frequency of the audio signal. The method is implemented by one or more processing chains including: A) a high-pass filtering of the digital audio signal having a frequency greater than or equal to 10 Hz and less than two thirds of the specific cutoff frequency of the transducer; B) performing a first low shelf filtering with a predetermined first amplification gain; C) estimating an excursion value of the transducer for the signal obtained after applying the first low shelf filter; D) if the estimated excursion value of the transducer exceeds the maximum excursion value, calculating a second amplification gain that is less than the first gain; and E) applying a second low shelf filtering of gain equal to the second calculated gain.

A headrest for a vehicle seat includes: a support surface for the head of an occupant; at least one lateral edge extending along an edge of the support surface; and a sound diffusion system arranged in a cavity in the edge and including a speaker configured to emit sound waves in front of the support surface and at least one passive radiator configured to emit low frequency sound waves in front of the support surface.
